It was extremely important because many families were broken apart due to the consumption of alcohol, mainly the man in the family. Many wives complained about abusive husbands and many parents got a divorce. That was not all, there were many religious and health concerns when it came to alcohol. The temperance movement did ban alcohol, but it didn't work. Many people went behind the law and started to create illegal places in which people could get access to alcohol. This was extremely dangerous and put many people in harm's way, causing the ban of alcohol to be put down, and the consumption of alcohol was once again, legal.
